Abstract

OBJECTIVE:

The purpose of this study was to investigate the pulpal response of dogs' teeth after pulpotomy and direct pulp protection with MTA Angelus, ProRoot, Portland cement and white Portland cement.

STUDY DESIGN:

Seventy-six teeth were treated with these materials. One hundred twenty days after treatment, the animals were sacrificed and the specimens removed and prepared for histological analysis.

RESULTS:

All the materials demonstrated similar results when used as pulp-capping materials. Pulp vitality was maintained in all specimens and the pulp had healed with a hard tissue bridge.

CONCLUSION:

The materials used in this study were equally effective as pulp protection materials following pulpotomy.
